Three beakers, an Erlenmeyer flask, a graduated cylinder and a volumetric flask. Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass.
Alternatively, a beaker may be covered with another larger beaker that has been inverted, though a watch glass is preferable. Beakers are often graduated, that is, marked on the side with lines indicating the volume contained. For instance, a 250 mL beaker might be marked with lines to indicate 50, 100, 150, 200, and 250 mL of volume.
Beaker (glassware) Many of these flasks can be wrapped in a protective outer layer of glass, leaving a gap between the inner and outer walls. These are called jacketed flasks; they are often used in a reaction using a cooling fluid.
Flat-bottomed flask: A flask with similar uses as the round-bottom flask, but with a flat bottom that allows it to stand on a level surface.; Florence flask: A flask similar to the flat-bottomed flask that has round bodies and either a round bottom or a flat bottom so that one can stand the flask on a level surface.
A Florence flask/boiling flask is a type of flask used as an item of laboratory glassware and is named after the city Florence. [1] It is used as a container to hold liquids. A Florence flask has a round body, a long neck, and often a flat botto
A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker. When used to cover beakers, the purpose is generally to prevent dust or other particles from entering the beaker; the watch glass does ...

The following footnote regarding the Marinelli beaker is found in a report by R.F. Hill, G.J. Hine and L.D. Marinelli (1950) of the Sloan-Kettering Institute in New York: "This equipment first designed by one of the present authors (L.D.M.) and in use in this laboratory since 1943, can now be obtained from Technical Associates, Inc.
